Nice work, Jadzia! That style of walls (where they appear to taper upward even though they're supposed to be rectangular) brings back memories. They don't make 'em like that anymore.

I'm working on a "game," too. I'm using pygame for it. As 2D engines go, it is probably the easiest one I've ever messed with. It's not as featureful as most engines but it gives you enough to get started so you don't have to write everything from scratch.
